About this add-on

Swarth modifies web pages to use a dark color scheme or based on the user's preferences. This extension is a fork of Dark Background and Light Text, rewritten to utilize XUL overlays instead of Jetpack/Add-ons SDK.

Several additional features were included, such as following the browser's preferred color scheme, keeping changes made in private browsing sessions, and sorting configured pages. You can use this extension alongside AutoPageColor to achieve automatic light/dark color scheme switching based on your current time, provided that you enable the Follow preferred color scheme.

Unlike DBaLT and its current derivatives, Swarth only targets pages opened in the main tab browser and the web panel/sidebar. Changes to the extension's settings (e.g., toggling enabled state and default color method) are not applied immediately on all windows and tabs. Instead, they take effect upon selecting or switching to a tab, fixing the minor but noticeable performance issue when enabling/disabling DBaLT's functionality while having many tabs open.
